dear all,

I have some data with name ZA000060.TXT, ZA000120.TXT, ZA000180.TXT ..... at the same time I load data with :

for k=60:60:300
    aa = sprintf('%d',k);
    load (['ZA0000' aa '.TXT'],'AAA')
end

but there is error when load second data because the zero number.

unable to read file "ZA0000120.TXT"

Any help would be great,

Best regard,

You didn't replace the ellipses with the filename. Specify the filename and it will work.

To elaborate on Walter's answer. We suspect the problem is that you need a variable number of 0s before the actual number, depending on the actual number of digits.

This is what the '%03d' does in the formatstring of sprintf. It says prints the number as decimal (the d) with at least 3 digits (the 3) padded by zeros if necessary (the 0).
